a) nAl= \(\frac{5,4}{27}=0,2\left(mol\right)\)
nSO3=\(\frac{16}{32+16.3}=0,2\left(mol\right)\)
nH2=\(\frac{0,8}{2}=0,4\left(mol\right)\)
nphân tử H2= (6.1023):(3.1023)=2(mol)
b) nSO2= \(\frac{4,48}{22,4}=0,2\left(mol\right)\)
=> mSO2= 0,2.(32+16.2)= 12,8(g)
mCO2= 0,8.(12+16.2)= 35,2(g)
c) nCO2=\(\frac{6,6}{44}=0,15\left(mol\right)\)
VCO2= 0,15.22,4= 3,36(l)
VN2= 0,15.22,4+3,36(l)
Sai chỗ nào ns cho mk bt nha
a.
\(n_{Al}=\frac{5,4}{27}=0,2\left(mol\right)\)
\(n_{SO3}=\frac{16}{80}=0,2\left(mol\right)\)
\(n_{H2}=\frac{0,8}{2}=0,4\left(mol\right)\)
\(n_{H2}=\frac{3.10^{23}}{6,023.10^2}=0,5\left(mol\right)\)
b.
\(n_{SO2}=\frac{4,48}{22,4}=0,2\left(mol\right)\)
\(m_{SO2}=0,2.64=12,8\left(g\right)\)
\(m_{CO2}=0,8.44=35,2\left(g\right)\)
c.
\(n_{CO2}=\frac{6,6}{44}=0,15\left(mol\right)\)
\(V_{CO2}=0,15.22,4=3,36\left(l\right)\)
\(V_{N2}=0,15.22,4=3,36\left(l\right)\)
